Over five months, this developer enhanced the AliceO2Group/O2Physics repository by building and refining flow analysis features for high energy physics data. They restructured histogramming logic to introduce a configurable Sample axis, enabling more flexible and reproducible analyses, and implemented Monte Carlo simulation support for validation and calibration workflows. Using C++ and advanced data analysis techniques, they improved track selection, event counting, and measurement precision by redefining default cuts and introducing new calculations for track merging. Their work focused on robust code integration, performance optimization, and clear data processing pipelines, resulting in deeper, more accurate physics analyses without introducing new bugs.

Jan 1, 2026January 2026 (2026-01) monthly summary for AliceO2Group/O2Physics. Focused on UPC flow analysis precision improvements that redefine default cuts, add a new dPhiStar calculation for more accurate track merging, and remove dependency on TPC cross rows in flow correlation and cumulant calculations, resulting in improved track selection and event counting accuracy. These changes enhance measurement precision and reduce systematic uncertainties in flow analyses.
